Dear Mrs. So and So ,
John Doe, from my daughter's class, scrated my daughter at the recess today.
I can understand that kids may accidentally scratch each other by an
inch or two, but these scratches run across over my daughter's whole
right forearm, more likely an intentional work. And he even did not
say sorry. Unfortunately, the picture does not fully reveal the
severeness of the scratches, the real scratches on her arm are worse,
still the picture gives you some sense how long the scratches are.
Please do something about it to minimize the chance of any similar
incidences to repeat.
